DEFECTLESS HYDROGEN SEPARATION MEMBRANE, PRODUCTION METHOD FOR DEFECTLESS HYDROGEN SEPARATION MEMBRANE AND HYDROGEN SEPARATION METHOD

摘要

The present invention provides a defect-free hydrogen separation membrane with high hydrogen selectivity and hydrogen permeability, a method for producing the same, and a method for separating hydrogen using the defect-free hydrogen separation membrane.;The present invention relates to a defect-free hydrogen separation membrane including a metal thin membrane that has a first metal layer of palladium formed on a porous support without substantial penetration into surface pores of the porous support and a second metal layer formed on the first metal layer by depositing palladium which also closes defects being open on the surface of the first metal layer.
